Abstract: A monitoring system, which comprises (a) a set of sensors comprising one or more orientation sensors and at least a state sensor mounted on a body, or in a relation to the body, the motion and state of which are monitored, wherein each of orientation sensor defines orientation and/or coordinates, where each state sensor measures the required state as a function of time for making decision based on a combination of orientation and state parameters; (b) a transmitter coupled to the one or more position sensors; (c) a control system including a timer, a processor for processing the measurement results and making decisions regarding the orientation and state of the body and a memory for storing data and operating software.

Abstract: An inflatable life-saving swimming garment for a swimmer that comprises an inflatable part for floating the swimmer while being in distress and for creating, when inflated, volume difference between upper body part and lower body part of the swimmer. The garment includes an inflating system that consists of a gas tank with compressed gas for inflating, whenever required, the inflatable part; a controllable valve connecting between the air tank and the inflatable part, for allowing, whenever required, the compressed gas to inflate the inflatable part; a controller for analyzing the swimmer's status underwater and opening the valve after the swimmer has been in an actual or impending distress for a predetermined time; and a battery for supplying power for the operation of the controller and the valve.
